Abstract

Six nights of Johnson V-band and Stromgren uvby β photoelectric photometry of the newly discovered δ Scuti variable HD 127759 were obtained during 1991 April 3 to 21. The period analysis, which employs Fourier periodograms and convergent least squares, indicates HD 127759 to be a single-sine frequency dominant pulsation variable, and the frequency is found to be 14.78626 cycle/d with an amplitude of A = 0.0199 m
